Eye Movement (sensory) - Anatomy - Neuroanatomy

Neuroanatomy

The brain exerts ultimate control over both voluntary and involuntary eye movements. Three cranial nerves carry signals from the brain to control the extraocular muscles. They are:

• III cranial nerve: Oculomotor nerve/Oculomotor nucleus
• IV cranial nerve: Trochlear nerve/Trochlear nucleus
• VI cranial nerve: Abducens nerve/Abducens nucleus

• Brain
  • Cerebral cortex
    • Frontal lobe – frontal eye fields (FEF), medial eye fields (MEF), supplementary eye fields (SEF), dorsomedial frontal cortex (DMFC)
    • Parietal lobe – lateral intraparietal area (LIP), middle temporal area (MT), medial superior temporal area (MST)
    • Occipital lobe
      • Visual cortex
  • Cerebellum
• Midbrain
  • Pretectal area – Pretectal nuclei
  • Superior colliculus
• Brain stem
  • Superior colliculus (SC)
  • Premotor nuclei in the reticular formation (PMN)
  • Paramedian pontine reticular formation
  • Cranial nerves
    • III: Oculomotor nerve/Oculomotor nucleus
    • IV: Trochlear nerve/Trochlear nucleus
    • VI: Abducens nerve/Abducens nucleus
  • Vestibular nuclei
  • Medial longitudinal fasciculus
  • Nucleus prepositus hypoglossi
